The BM 710 seems to fit your requirements just about perfectly.
And it is a great knife.
Spydie Chinook? Already mentioned I see...
Also sounds like something you'd like. Big. Lockback. Great.
Interesting, once you move above the $140 or so range you don't see a lot of lockbacks. Instead you get a lot of linerlocks and framelocks.
Ernie Emerson's knives, for example. But they are great knives.
You could look at the Hossom Retribution, BTW. Linerlock though.
And with the Benchmade, Spyderco, Emerson and Ontario you're looking at 3-4 different bladesteels.
If you like D2, there's the 710. I happen to really like D2. 154CM? Emerson. Etc.
Anyway, as you suggest, you can save up and move into Sebenza range, and a bit more you can go custom. Maybe by the time you're ready Jerry Busse will even have released his folder.
But I wouldn't bet the house on that...
